A mobile machine for distributing and shaping the ballast bed of a railroad track comprises a machine frame, and a ballast plow arrangement comprising a ballast planing plow including two vertically adjustable center plowshares arranged between the rails and a respective rail-bridging tunnel-shaped element associated with each rail and embracing the associated rail. A vertically adjustable, transversely extending ballast scraping and damming wall is arranged between the tunnel-shaped elements immediately behind the center plowshares in the operating direction, the wall having an upper edge, and a conveyor band is arranged immediately behind the ballast scraping and damming wall for removing any ballast flowing over the upper edge of the wall. |
